Examples of Natural Selection

Mr. Anderson discusses natural selection and evolution, focusing on real-world examples. He explains how climate change affects species, using Glacier National Park and Thoreau's observations as examples. The video covers mutations and their impact on phenotypes, highlighting sickle cell anemia and its evolutionary implications. Finally, it addresses human-induced changes, such as antibiotic-resistant bacteria, emphasizing the importance of responsible antibiotic use.
